Abstract：Piezoresistive tactile sensor array technology is one of the most promising practical technologies. By using piezoresistive elastic sensitive film and reasonable electrode lead, it can be made into a soft "tactile skin", which is suitable for different applications. As the number of tanctile sensors in the array increases, the scanning and sampling mode based on a single tactile unit will seriously affect the sampling rate of a single frame tactile image.In this paper, a piezoresistive array automatic test and analysis system based on line-scan technology is designed and produced, which greatly improves the speed of tactile sampling. The improving of the tactile image sampling frequency, creates conditions for real-time processing of the whole tactile system.The experimental results show that the automatic test and analysis equipment can display the force size and orientation on the tactile sensor array in real time and accurately, and the method can be used to other different piezoresistive sensor array tests.
